Means for Divided Differences and Exponential Convexity

Mediterranean Journal of Mathematics, 2011
In this paper we obtain two means for divide differences using two majorization type results where one is related with Schur convexity. We examine their monotonicity property using exponentially convex functions.

Convexity, monotonicity, and positivity results for sequential fractional nabla difference operators with discrete exponential kernels

Mathematical Methods in the Applied Sciences, 2021
We consider positivity, monotonicity, and convexity results for discrete fractional operators with exponential kernels. Our results cover both the sequential and nonsequential cases, and we demonstrate both similarities and dissimilarities between the ...

Hermite-Hadamard type inequalities via new exponential type convexity and their applications

Filomat, 2021
In this paper, authors study the concept of (s,m)-exponential type convex functions and their algebraic properties. New generalizations of Hermite-Hadamard type inequality for the (s,m)-exponential type convex function ? and for the products of two (s,

Convexity preserving interpolation with exponential splines

Computing, 1986
Sufficient and necessary conditions are derived under which interpolating splines are convex if the data set is in convex position. In order to select one of the interpolants, by means of a well-known objective function a quadratic optimization problem is stated which can be solved effectively by passing to a dual program.

Exponentially convex univalent functions

Complex Variables, Theory and Application: An International Journal, 1997
In this article we introduce the tamily e(α), α ∈ C. of α-exponentially convex functions f as normalized univalent functions in the unit disk D such that e αf is convex univalent. Out study was suggested by a formal and concrete relationship between e(α) and the class of convex functions of bounded type, defined by Professor A. W. Goodman.

Exponential TEM horn with a convex triangular arc

2013 Africon, 2013
TEM ahorn antennas are well known for their ultra-wideband capabilities and are widely used. However, axial symmetry of the radiation pattern over such a wide frequency band is difficult to achieve. In this paper, a modification is proposed to the exponential TEM horn in the form of a convex triangular arc at the mouth of the antenna.

Exponential Convexity Method

Journal of convex analysis, 2013
In this paper generalized Stolarsky and related means are recognized as an application of particulary defined linear functional on family of n-convex function. However, this approach leads to a more general method of constructing exponentially convex functions and means of Cauchy type.
